Oh no. How can you treat r/bitcoin and r/btc as news sources? They're basically in a civil war with each other and I wouldn't trust these subreddits much. But I like the idea of some kind of list where all cryptocurrency news sites will be. How about setting up a simple website? I, unfortunately, don't currently have time to do this, but others might have enough time...
Amidst the mudslinging they do provide one of the best forums for quickly catching breaking news as it gets upvoted. Just wear body armor and wash up after you've been in either one...
